Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed August 19, 1907. Serial No. 389,198.

To all whom it may concern: if

Be it known that LGILMORE M. Yos'r, of Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Yises, of which the following is a specificat1on.

My invention relates to. a universal vise and is designed to provide a construction whereby the vise may be attached by a hinge to the edge of the top of a work bench without reducing the thickness of the top of the bench, and to provide a very simple and strong construction and one which will permit the turning of the jaws in a lane at right angles to the normal travelof t e movable jaw withoutldisturbing the work.

It also relates particularly to simpleand efficient means for adjusting the angular relation between the faces of the jaws of the vise.

My invention consists of the matters illustrated in the drawings, described in the s ecification, and more particularly pointe out in the appended claims. j

Referring to the drawings: Figure 1 is a pers ective view of the vise in position on the enc Fig. 2 is an inverted perspective view of the same. Fig. 3 is a transverse section on the line 33 Fig; 6. Fig. 4 is a horizontal section in the plane of the feed screw, the screw being shown in full. Fig. 5 is a detail erspective view of parts of the adju'stin mec amsm. Fig. 6 is a vertical longitudina section, in the plane of the feed screw, the screw being shown in full. .Fig. 7 is a perspective view of the longitudinally stationary jaw.

The vise is su ported from the work bench 1 by means of a hinge 2 having the leaf which is attached to the work bench provided with a vertical portion 3, and a horizontal portion 4, which is attached to the underside of the bench. The other leaf of the hinge 5 carries a split sleeve 6 provided with lugs 7, one of which has a cam surface with which a cam lever 8 working on a bolt 9 cooperates to clamp and unclamp the sleeve. The vise is provided with a jaw 10 not longitudinally movable and with a traveling jaw 11. The jaw'10 is providedwith a hub 12 which I make integral with the jaw and the axis of which is located to one side of the longitudi nal median line of the jaw. This constructionsupports the viseso that it does not in terfere with the work bench nor require the weakening of the to of the bench by cutting away a part of its t ickness as is commonly necessary. The parts are so proportioned that the sleeve 6, when the vise is 1n normal position, rests firmly against the underside of the horizontal portion 4 of the hinge. The hub 12 forms a large bearing surface in the sleeve so that the jaw 10 may be rotated in a plane at right angles to the line of travel of the other jaw and firmly supported in any osition. The split sleeve 6 and the cam ocking arrangement above described make it possible to secure any adjustment desired, the adjustment not being limited to a series of adjustments at fixed distances. The sleeve 6 is, however, provided with a spring pressed pin 6 which cooperates with corresponding depressions 6 in the back of the jaw 10 adjacent the hub 12 to locate the jaw in the desired positionas with its longitudinal median line horizontal,so that by the useof the cam lever 8 the precise adjustment thus indicated and temporarily secured may be made permanent. This, of course, does notlimit the range of adjustment in any way. The hub 12 is provided with a square hole 13 in which fits slidably the supporting bar 14. The hub 12 is also rovi ed with a screw-threaded nut 15 whic as shown is held firmly in an under cut groove 17. This may be accomplished by driving the projection 15 of the nut into the groove, the cooperating parts being, if desired, wedge shaped to sustain thepressure developed in the use of the vise. Usually, and as here shown, a pin 16 is also employed.

Thebar 14 is provided with a slot 14 to permit its longitudinal movement. This bar is hollow to accommodate the feed screw 18 and is rovided with a head 19, having a removab e finger 19 cooperating with a groove 18 in an enlarged portion 18 of the feed screw :18 to prevent it from moving longitudinally with respect to the bar 14. This bar has a head 19 which serves as a support for the traveling jaw 1 1, the latter having an enlarged hole throu h which the bar passes and being pivoted to forked projections 20 of the said head by a pin 21 passing through said working outside of and against said projections 20. The other end of the head is provided with forked projections 22 in which is mounted rotatably a bearing block or pin 23 through which works a screw-threaded adjusting pin 24. A ball and socket joint is provided between the end of this pin and the rear face of the jaw 11. As shown, this is made up of a socket 25 in the jaw and a ball 26 which is fastened on the end of the pin in any suitable manner. A detachable cap 27 permits the parts to be assembled and holds the joint in position. For convenience the head 28 of the adjusting pin 24 is made removable so that the plate 29 which covers the parts just referred to may be readily removed.

The pin 23 has a flattened portion 23 parallel with its own axis and at right angles to the axis of the pin 24. This portion 23 constitutes one vmember of a stop, the other member of which is the cap 27 on the jaw. This stop mechanism supports the jaw against the head of the bar, relieving the adjusting means and especially the pin 24 of strain, when the aw faces are in normal relation. These parts as illustrated are arranged to sup ort the travelin jaw with its face in paralle ism with that of the other jaw with out imposing any strain on the adjusting pin 24, which at the time specified is not in action.

To the sleeve 6 is attached a bar 30 which passes through a clamp 31. This clamp comprises a split standard 32 controlled by cam locking mechanism 33 such as already described in connection with the split sleeve. By these means the vise may be held firmly in any position of the hinge.

What I claim as new is:
